Which kind of aquatic ecosystem does the photograph most likely - 1

Answers

Answer 1
Answer:

The correct answer is D. River

Explanation:

Rivers are one of the most common ecosystems. A river is characterized by flowing water in which biotic factors (animals, plants, bacteria, etc.) and abiotic factors (rocks, water, minerals) interact. Also, they cross major ecosystems such as forests or rainforests.

Moreover, rivers are unique because they contain fresh rather than salt water as in the ocean, and they are always flowing while in a marsh, swamp or lake the water does not flow. This suggests the ecosystem is the photograph is a river because in this the water flows and as a result of this, there is a strong current which is possible in a river but not in a lake, marsh or swamp.

c. has a negative electrical charge.
d. has a maximum temperature of 1 million°C.

Answers

Answer:

b. is made of superheated gas.

Explanation:

Most atoms in the Sun exist as plasma, or a fourth state of matter made up of superheated gas with an electrical charge which is both positive as well as negative.  Our Sun consists almost entirely of the elements hydrogen and helium. ... The core is plasma, but moves similarly to a gas.  Its temperature is around 27 million degrees Celsius.  And because the Sun is not solid, it does not have a defined outer boundary.

Hope this helps!!

b. is made of superheated gas.
